Hi Desi,


Tens machines here are available at pharmacies for anyone to purchase.
There seems to be little regulation or advice that they need to be used only on medical advice.
My tens (which I can't use, too painful) has pads that the gel is actually compacted into it, it doesn't wipe off onto your hands but it feels a bit cool to touch.
I think most Tens units have this type of pad now as this is what is required to help transmit the impulses.
I don't think you would harm yourself but it can be very painful if the strength or length of the impulse is set too high. I used to start off at a low rate and work my way up.
I also admit that I did not clean my skin specifically before application but again this would be just to ensure there is no greasiness that would block the impulse.
For me I will never use it again I found it just too painful, I do know some people who find otherwise and swear by it.
Perhaps your PT could check the settings to see if perhaps they are just set to high and maybe it will be a useful option for you---let's hope so.
Good luck
Tayla
